Method for producing α-hydroxy acid |
| abstract |
An object of this invention is to provide the manufacturing method of the alpha-hydroxy acid which is economical and has sufficient quality as a polymer raw material, without producing a lot of waste as a by-product. The present invention includes a step of producing an α-hydroxy acid metal salt by adding basic metals to an α-hydroxy acid ammonium salt, and desalting the α-hydroxy acid metal salt to produce an α-hydroxy acid. And a process for producing an α-hydroxy acid comprising the steps. |
